    Portable non-mydriatic device closes gap on tele-glaucoma screening

    Imaging system can help patients in remote areas, those not able to reach centers

    Ann Arbor, MI—As clinicians look for better ways of glaucoma screening for patients in remote areas of the world or those who cannot mobilize easily, accurate and portable equipment plays a huge role.

    When ophthalmologists in a study graded optic nerve photographs taken with a portable non-mydriatic camera (Pictor, Volk) and a standard table-top mydriatic camera (Topcon), there was not a significant difference in the measurement of cup-to-disc size between cameras, said Paula Anne Newman-Casey, MD, MS.

    In many parts of the developing world, it is difficult for people to travel to eye clinics for routine screening. This is especially the case in Nepal, where the study took place. To screen for cataracts, for instance, teams of eye-care providers will travel for days and hike for hours, or even a day, to reach remote villages.

    “There’s a real need for portable equipment,” said Dr. Newman-Casey, assistant professor of ophthalmology and visual sciences, Kellogg Eye Center, University of Michigan, Ann Arbor.

    Quality matters

    However, in the rush for portable devices, there sometimes has been less of a focus on whether the device is of high enough quality to ensure good clinical outcomes.

    The current study aimed to evaluate whether a new portable fundus camera that does not require dilation would produce reasonable enough photographs to allow ophthalmologists to accurately assess the cup-to-disc ratio compared with standard technologies.
